Baby joy helps soften grief

When Zayn Topperwien was born, his parents, Ryan and Keri, were overjoyed - but the emotion was bittersweet.

Baby Zayn is the younger brother of Chace, the 3-year-old who had a rare and aggressive form of leukaemia that claimed his life in June 2012.

The grieving Whakatane couple immersed themselves in The Dream Chaser Foundation - A Chace Topperwien Charity, set up in their little boy's memory to help other cancer-stricken children.

So when Mrs Topperwien discovered she was pregnant with Zayn last year, it was a "mixed bag of emotions".

"The difference is now - and this is something a lot of mums who have been through a loss feel - I don't have that kind of naive outlook on life any more," Mrs Topperwien said.

"I know that bad things can happen and I know bad things can happen to my children, so I was worried about the pregnancy."

Zayn's slightly early arrival on January 30 brought immense joy to the couple and their families, but there was still a sense of loss.

"It's obviously made us really happy and given us something positive, but at the same time Chace is always on our minds," Mrs Topperwien said.

"We were happy and sad," Mr Topperwien said. "We were happy that Chace had a brother but sad that Zayn didn't get to meet him."

Though he resembles his brother, Zayn was "growing into his own little person", Mrs Topperwien said.

They named him Zayn Chace, after his brother, who would have turned 5 next Monday.

Today is the third anniversary of Chace's cancer diagnosis, which made headlines because at his six- week immunisations a nurse mistakenly injected him with Gardasil, a vaccine to prevent cervical cancer.

By the time Chace was 2, he had developed a rare and aggressive strand of acute myeloid leukaemia, but doctors said they couldn't know whether it was related to the Gardasil.

The Topperwiens raised tens of thousands of dollars for treatment for their son, including for a drug trial in the United Kingdom.

On Tuesday, Zayn also had his six- week immunisations and Mrs Topperwien said they asked nurses to triple check the contents.
